OIL-CAN.

SPECIFICATION" forming part of Letters Patent No. 320,759, dated June 23, 1885.

Application filed January 7. 1885.

oil-cans, which economize their construction and render them more convenient in use, as hereinafter fully explained.

In the accompanying drawings, Figure 1 is a vertical section of a can and pump embodying our improvements. Fig. 2 is an enlarged section of the lower part of the pump-well, together with an external view of the lower part of the pump, the nut and packing-ring being shown in section. Fig. 3 shows the lower packing'ring detached. Fig. 4. is a diagrammatic representation of the first step in the process of joining the bottom to the body. Fig. 5 is a section of the upper body-margin and adjoining portion of the top plate.

A represents a can embodying our improvements. The body B of said can has its lower edge, I), folded (preferably twice, as shown in Fig. 4,) inward to receive the down-turned marginal flange c of a sheet-metal bottom 0. These parts having been engaged, as shown in Fig. 4, are tightly compressed together and flared outward, as shown in Fig. 1. This mode of construction causes the body and the bottom to become so tightly interlocked as not to be drawn apart by the application of the solder D.

Before application to the body, as above, the bottom 0 has had formed in it an annular depression or channel, c,"which coacts with the outflared and tightly-inclosed margin 0 to prevent any wrinkling, buckling, sagging, or shrinking out of the bottom, either under action of the soldering-bitor in subsequent use. The said channel is further useful as a conduit or passage-way for oil from the can-body into the interior of the pump-well, and, besides securing more perfect drainage, supersedes the necessity of providing orifices for that purpose within the well-wall itself, though such orifices may also be used to afford additional passageway to the pump-well, when desired. The can-body B has its upper margin folded (preferably twice) outward and downward, inward (No model.)

and upward, as shown at F, Figs. 1 and 5, and has near and parallel to its said margin an annular inwardly-directed bead, b, which, besides serving to stiffen the body at this part, affords an accurate support for the top plate, E, during the act of soldering it to the body. By this mode of construction of the entire canedges, conveXly-rounded exteriors are secured having no out edges exposed to view. The top plate, E, has a central sink or depression, e, whose inturned neck 6 may receive'any cork, plug, .or stopper, G.

H represents one of two ears for a customary bail, I.

A portion of the top plate, E, near one side of the can, has a screw-threaded riser, J, to which is attached the upper end of a tube, K, constituting the pump-well, preferably of cylindrical form, and having its lower end sol dered to the can-bottom so as to straddle the channel 0, and to thus afford two passages, of which one is seen at c, from the interior of the can into the said tube K, and to thus render unnecessary any special inlet-orifices in the well-wall. The riser J (or the upper part of the tube K) has a flaring mouth, j, for the ready insertion of the tube or barrel L of our oil-pump, which pump is capable of being shifted up or down, telescopewise, and of remaining at any desired elevation within the said well K, or of being easily withdrawn from or inserted within said well.

Our said pump-barrel L terminates below in a screw-threaded foot, M, having a central orifice, m, that constitutes the inlet-port, and having a conical shoulder, m. The screwthreaded part m of said foot takes a nut, N, which has preferably a like conical shoulder, it. These conical shoulders, together with so much of the well-wall and of the screw m as are included between them, constitute an annular space for reception of a corresponding packing-ring, O, which is preferably composed of leather. The pump having been withdrawn from the can, the packing-ring 0 may be caused to fit with any desired tightness within the well for self-retention at any height at which it may be placed without such excessive friction as to make it too difficult to change its level when desired. Resting upon the fiat top of the foot M, and confined by a grating,

Q, is a small metallic disk, 1?, that constitutes the inletvalve. The pump -barrel is surmounted by a chamber or enlargement, R, which has, in alignment with. said barrel, a screw-threaded neck, S, for a corresponding screw-threaded cap, T, whose central orifice, t, receives and guides the rodU of the pumpplunger or piston V. A recess, in said cap contains a washer, XV, preferably of leather, which prevents outspurting of contents at the extreme upward stroke of the plunger. Small orifices k in the upper part of the well-wall, just below its junction with the can-top, enable complete drainage from the can of whatever the pump has not removed. After removal of the pump the can may be closed for convenient transportation or safe stowage by application of a screw-cap, X, to the screw threaded riser J. This cap is preferably suspended to the cam by means of a chain, Y.

The expansible packing-ring 0 possesses several obvious advantages besides those above enumerated. For example, it enables selfcompensation for slight inequalities of diameter of the inclosing-well, and thus obviates necessity of such accurate work as would render the manufacture too expensive.

A manifest advantage arises from the attachment of the packing O to the pump rather than to the well, since simple withdrawal of the pump gives immediate access for adjustment, as aforesaid. The said packing is also free from a common objection to telescoped pumps of liability of the packing material, on every removal of the pump, to fall into and obstruct the Well-space.

The above-described preferred form of our improvements may be varied in minor particulars. For example, the conical surface may be restricted to the foot M, the same being associated with a common flat nut.

The parts here described to be of leather may be composed of any other suitable material.

The inlet-valve may be located in the lower part of the pump-well,instead of in the pump barrel proper. W

\Ve claim as new and of our invention- 1. The combination, with an oil-can, of the pump-well K, having its lower end fixed 5o athwart the annular depression or channel 0 of the can-bottom, substantially as set forth.

2. The combination, in an oil-can,ofthe body B, the bottom 0, and a pump-well, the body having folded lower edge, I), the bottom having oil-conduit c and flared downturned marginal flange c embraced by the folded lower edge and soldered thereto, the pump-well be ing secured athwart the oil-conduit.

In testimony of which invention we hereunto set our hands.
